BULLETIN 1034, U. S. DEPARTMENT OF AGRICULTURE. 



to 1920. (See Table 6.) The yield of cotton in 1913 was very close 

 to that of the State average for the five-years 1911 to 1915, but the 

 yield for 1918 was much above that of the average for the five-year 

 period 1916 to 1920. The average yield for the latter five-year 

 period fell more than 20 per cent below that of the former. The 

 yield per acre of cotton for Georgia in 1913 is given at 82.6 per cent 

 of normal, and in 1918 at 71.11 per cent. The losses from normal 

 yield for each year are assigned to causes shown in Table 7. ■
